[Bug c/15414] New: Failure in compiling very huge C program

["gprizzi at tin dot it" <gcc-bugzilla at gcc dot gnu dot org>]

Dear sirs

I am working with Politecnico of Milano on a project for ESA.
I have a problem and I hope you can kindly suggest me a way to solve it.

I got a failure in compiling a very big C source code, automatically generated 
by a tool for dynamic multi body simulation.
The source file is 21 MB and the preprocessed file is about 14 Mb in size.

The output of the compiler is the following:
cc1: Cannot allocate 4228939388 bytes after allocating 14476768 bytes
 /usr/lib/gcc-lib/i486-slackware-linux/3.2.3/cpp0 -lang-c -v -I. -
I/root/dymola/source -D__GNUC__

I am working on an Intel work station with:
PIV 3Ghz
1 GB RAM
Linux operting system - slackware 9.1
Gcc version 3.2.3

The command line I used for the compilation is the following:

gcc -v -save-temps -o dymosim -O -DDYMOSIM -DUNIX -DSkip_f2c_UNDEFS -I. -
I/root/dymola/source 
dsmodel.c /root/dymola/source/dymosim.c /root/dymola/bin/libds.a /root/dymola/bi
n/librtai.a -lm -lcomedi >logs.txt 2>&1

and the following is the output of the command:

I have the preprocessed file but how can I sent it to you?

Please can you suggest me how can I get my source code compiled?

Thank you in advance for your help.
